Platypus QuickDraw MicroFilter System Review

Bottom Line

The Platypus QuickDraw MicroFilter System is an extremely straightforward and convenient way to make water from natural sources safe to drink. The build quality is among the best of any squeeze filter on the market, and we love how easy it is to backflush and check its integrity.

We recommend the QuickDraw for those willing to pay a few bucks more for excellent durability and a high-quality reservoir. Overall, we think it is a great filtration option.

Water Quality

Drinking bad water can quickly ruin a trip and wreak havoc on your body for weeks or months. It’s best to filter all water in the backcountry to avoid contracting a gnarly stomach parasite. The QuickDraws hollow-fiber filter cartridge removes 99.9999% of bacteria and 99.9% of protozoa. It’s effective against giardia, salmonella, and cryptosporidium – the most common things you’ll encounter on the trails in North America. It also does a great job of clarifying water by removing small debris particles.

The QuickDraw Filter does an excellent job of removing the most common bacteria and protozoans you’ll encounter while backpacking in the US, but it doesn’t kill viruses. However, if you’re hiking where water-borne viruses are a concern, you may want to pair it with a chemical treatment. Katadyn’s Micropur Tablets or a purifier like the Katadyn Steripen or MSR Guardian are great options.

Ease of Use

The QuickDraw filter cartridge has dual inside and outside threads, so it can be attached to a variety of bottles and reservoirs. We almost always use the 1 L reservoir that comes with the filter, but we appreciate that it’s compatible with smartwater bottles and a variety of other beverage containers. Versatility is always good, and if the reservoir had a blowout, we’d have a backup.

We also appreciated that the QuickDraws microfilter attaches to the outside of bottles and reservoirs. Some filter designs, like the Katadyn BeFree and LifeStraw Peak Squeeze, nest the cartridge inside the reservoir, which makes it a) difficult to squeeze every last drop and b) impossible to fit in a whole liter of water. It’s helpful to store a full liter in the ‘dirty’ reservoir and know that you’re filtering exactly 1 L of water into an empty water bottle of your choice.

We’ve been using Platy Bottles on backpacking trips for ages, and we trust them to be durable and taste-free. We’ve had good experiences using the 1 L QuickDraw reservoir that’s included with the filter, and they’re more durable than the bags that come with the Sawyer Squeeze. The QuickDraw reservoir has a wide mouth that makes it easy to fill at water sources. And it has a great little handle that makes it easy to carry in your hand if you’re drinking right out of the bottle on the go. It’s also nice for scooping water from a cold source without submerging your hands on chilly trips.

We usually keep the QuickDraw filter attached to the squeeze reservoir at all times, only taking it off to refill. Suppose you prefer to carry the parts separately for better packability. In that case, you’ll need to carry a couple of additional caps (included) – one for the dirty side of the filter cartridge and another for the reservoir.

It’s a minor gripe, but it can be a bit of a chore to keep track of these loose caps (both on the trail and in the drying rack/gear storage box at home). It would be handy if Platypus designed the caps with holes and tethers to keep them attached for those who choose to use them. Until then, we recommend keeping the caps in a Ziploc when not in use. Remember, they’re contaminated, so don’t let them come into contact with clean bottles or water.

Squeeze filters, like the QuickDraw, are generally best for trips that have frequent, clear water sources along the route. Squeezing 1 or 2 L with the QuickDraw in a session is a snap, but squeezing can become tedious if you frequently need to ‘camel up’ with more than a few liters at a time for long carries or dry camping. In that case (or if you’re traveling with a group), you might want to consider something that requires less physical effort, like the Platypus GravityWorks.

Treatment Time

There’s no wait time when using the QuickDraw, unlike chemical or UV treatments. Scoop water from a natural source, squeeze it through the filter into a bottle, and it’s immediately safe to drink. We can easily filter multiple liters in a minute or two, which helps keep breaks short. Sometimes, we don’t even bother stopping. If you keep the QuickDraw accessible, and there are frequent water sources along the route, it’s easy to grab a liter on the fly. We often filter while walking or drink straight from the cartridge.

Hundreds of tiny, hollow fibers allow the QuickDraw to filter water rapidly. Platypus claims it can filter up to three liters per minute with normal squeeze pressure. We don’t often backpack with a three-liter reservoir, so we haven’t tested that theory, but three liters per minute seems like a stretch to us. That said, we’re more than happy with the QuickDraws ability to process one liter of water in less than a minute (about 40 seconds).

The QuickDraw is fast when it’s new. Unfortunately, as is the case with all squeeze filters, the hollow fibers that make up the membrane can get clogged, and the flow rate will eventually slow down over time. We recommend choosing water sources carefully and, if necessary, pre-filtering water that’s super silty or full of debris to increase the lifespan of your filter and maintain a good flow rate.

If you know the area where you’re hiking has silty or highly contaminated water sources, the QuickDraw (or any squeeze filter) might not be the best choice. Those conditions will slow your filter down, and treating water could become quite a chore by the end of your trip.

Weight

The QuickDraw system is incredibly lightweight compared to traditional pumps and filters. The dry microfilter weighs a mere 2.3 ounces (or 3.6, including the one-liter reservoir), so it’s perfect for anyone looking to minimize pack weight. That’s a tad lighter than the Sawyer Squeeze (2.5 ounces without reservoir) and a bit heavier than the Katadyn BeFree (1.2 ounces without reservoir), but the difference is negligible.

The saturated QuickDraw cartridge with both caps weighed 3.1 ounces on our scale. If you keep your filter attached to the squeeze reservoir as we do on the trail, you may choose not to carry the additional caps, which will shave off about 0.4 ounces from the total weight.

The QuickDraw filter cartridge fits easily in a hip belt pocket or fanny pack, and the reservoir folds completely flat when not in use. We love how small and space-saving this system is. It’s so minimal that we often bring it in a pocket on trail runs so we don’t have to carry a water bottle.

Maintenance & Longevity

One of QuickDraw’s biggest upsides is its durability. The flip-open sports cap is much stouter than those on the BeFree and Sawyer and won’t threaten to break off after repeated opening and closing. The whole filter cartridge feels solid in your hand, and even the caps are made of thick material. The QuickDraw is probably the most durable squeeze filter on the market, so it’s great for thru-hiking or anyone tough on gear.

All water filters slow down over time as they’re exposed to particulates in water, and backflushing can help restore their flow rate. Some filters require a syringe to force water back through them, but you can flush the QuickDraw with nothing more than a clean water bottle. In our experience, a vigorous shake will also work well to maintain the flow rate in the field. But, if the QuickDraw needs a more thorough backflushing, you can invert a bottle full of clean water over the drink spout and squeeze water back through the cartridge.

If you know the area where you’re hiking has silty or highly-contaminated water sources, the QuickDraw (or any squeeze filter) might not be the best choice. Those types of conditions will slow your filter down and treating water could become quite a chore by the end of your trip.

If temperatures dip below freezing, keep the QuickDraw close to your body while hiking, and keep it in your sleeping bag at night. If water freezes inside the filter, the pores will permanently enlarge, and the filter will be unreliable against protozoa and bacteria. At home, don’t store squeeze filters in a garage, basement, or shed subject to sub-freezing temperatures.

There’s no way to visually tell if hollow fibers freeze has occurred on many squeeze filters, so you’d have to discard them if you were worried. Thankfully, there is a way to check the integrity of the QuickDraw. Follow the instructions provided by the manufacturer to determine whether your filter is safe to use.

Should You Buy the Platypus QuickDraw Microfilter?

The QuickDraw is slightly more expensive than the comparable Sawyer Squeeze. That said, it’s still an excellent value, and we don’t mind paying a few dollars more to get the high-quality reservoir that comes with it.

Platypus claims you should be able to filter 1,000 liters of water with a QuickDraw cartridge, which pencils out to about $0.05 per liter. Compare that to the cost per liter of treating with chlorine dioxide drops and pills (~$0.50 per liter), and Aquamira Drops (roughly $0.13).

In the grand scheme, this system is affordable, easy to use, and minimal in weight. So long as you’re willing to properly maintain the QuickDraw to get many trips out of it, it’s a great piece of gear to have.

What Other Water Filters Should You Consider?

Katadyn BeFree Review: If you’re looking for something even more minimal and lightweight, and where the filter is housed inside the bladder, the Katady BeFree is worth exploring.

Katadyn Micropur Water Tabs Review: The QuickDraw is significantly heavier and bulkier than a chemical treatment like Katadyn Micropur Water Tabs (1.2 ounces for 30 tabs). So, if you’re looking for the most ultralight and minimal option, a treatment like this might be a better fit.
